A method to control a road vehicle provided with a dual-clutch, servo-assisted transmission and standing still with the internal combustion engine turned on; the control method comprises, when the road vehicle is standing still with the internal combustion engine turned on, the steps of: engaging a forward gear associated with a first clutch; engaging a reverse gear associated with a second clutch, which is different from and independent of the first clutch; closing the first clutch so as to cause the first clutch to transmit a first torque; and closing the second clutch so as to cause the second clutch to transmit a second torque, which is equal to the first torque multiplied by the quotient between a gear ratio of the reverse gear and a gear ratio of the forward gear.

Methods and systems are provided for operating a driveline of a hybrid vehicle powertrain, where the driveline includes an electric machine downstream of a dual clutch transmission, which is downstream of an engine. In one example, a method comprises communicating from a transmission, a torque to accelerate transmission components from a first speed to a second speed with first and second clutches of a dual transmission open, the communicating performed while an electric machine coupled to the dual clutch transmission at a location downstream of the dual clutch transmission is providing torque to propel a vehicle. In this way, wheel speed may remain substantially constant while the transmission is shifted and the engine is stopped.

A brake control device is a control device for a vehicle used in a vehicle on which the shift-by-wire system and the brake-by-wire system are mounted. A function of automatically operating the brake device without an operation of the driver of the vehicle is referred to as a BBW automatic operation function, and a request by the driver for disabling the BBW automatic operation function is referred to as a disabling request. A brake control device includes a disabling determination part configured to determine a presence or absence of the disabling request, the vehicle stop determination part configured to determine whether the vehicle is stopped, a slope determination part configured to determine whether the vehicle is located on a slope, and a BBW automatic operation part. The BBW automatic operation part operates the brake device when the vehicle is stopped on the slope even if the disabling request is made.

A powertrain optimization method is used to identify the optimal torque operating range. The method for controlling the vehicle includes: receiving, by a planning controller, a trip plan based on an input from a vehicle-operator, wherein the trip plan is indicative of a planned trip; determining, by the planning controller, a current location of the vehicle using a Global Navigation Satellite System (GNSS) of the vehicle; determining, by the planning controller, a geography of the planned trip using map data from a map database; determining, by the planning controller, a target speed profile for the vehicle as a function of the trip plan, the geography of the planned trip, and a predetermined, optimal acceleration range; determining, by an adaptive cruise controller, a torque request as a function of the target speed profile, a predetermined-optimal torque range, and a current speed of the vehicle.

A hybrid vehicle and a method of calibrating a traveling direction of the hybrid vehicle are disclosed. The method of calibrating a traveling direction of a hybrid vehicle including a transmission not having a reverse gear includes: when an abnormality of a motor speed sensor is detected, calculating a difference between at least one of a first moving distance calculated based on sensor information during a predetermined time or a second moving distance calculated based on output torque and a third moving distance calculated based on a vehicle speed by a controller for controlling output torque; when an absolute value of the calculated difference is greater than a preset error reference, reversing the traveling direction recognized by the controller; and controlling a powertrain in response to a transmission lever state.

A system includes a first sensor configured to detect a rotational position of a first wheel. The system includes a second sensor configured to detect a rotational position of a second wheel. The system includes a third sensor configured to detect a rotational speed of a driveline operatively coupled to the first wheel and the second wheel. The system includes a computer in communication with the first sensor, the second sensor, and the third sensor. The computer is programmed to detect a fault associated with the first wheel or the second wheel based on a correlation between an oscillation in the rotational speeds of the driveline and the rotational positions of the first wheel or the rotational positions of the second wheel.

A system for controlling load sharing between multiple generators mechanically coupleable to the output shaft of a prime mover is provided. The system may comprise a first processor; and at least two inverters operably connectable to at least two generators, respectively. The generators provide AC power to the respective inverter and each inverter provides DC power to a respective DC link. Each inverter may comprise a processor configured to control a respective generator. The processor may be configured to receive a common speed command from the first processor, adjust the common speed command based on a speed of the same output shaft to create a droop, determine a torque command based on the adjusted speed command and supply the determined torque command to the corresponding generator.

Methods and systems are provided for operating a driveline of a hybrid vehicle that includes an internal combustion engine, a rear drive unit electric machine, an integrated starter/generator, and a transmission are described. In one example, inertia torque compensation is provided to counter inertia torque during a power-on upshift.

A powertrain system for a vehicle is described, and includes an internal combustion engine that is selectively coupled to a driveline. The engine is configured to operate in a coasting mode, wherein the coasting mode includes operating the powertrain system with the engine in an OFF state and decoupled from the driveline. Devices are configured to monitor an output torque request, vehicle speed, and vehicle operating conditions. An executable instruction set monitors the vehicle speed and the output torque request. The engine is controlled to operate in the coasting mode when the output torque request is within the predetermined torque region and the vehicle speed is greater than a minimum speed threshold. The engine is controlled to discontinue operating in the coasting mode in response to the output torque request being outside the torque region of the vehicle speed being less than a minimum speed threshold.

A method of controlling a gear shifting in a neutral gear stage for shortening a gear shifting time in the neutral gear stage when performing a gear shifting of a hybrid electric vehicle is characterized in that when a shift class of the gear shifting is determined, a hybrid control unit of the vehicle determines a shift gear ratio in the N-stage in a current state by use of a transmission (TM) output speed and a transmission (TM) input speed at a class transition time point, determines an N-stage gear shifting progressing rate by use of the determined N-stage shift gear ratio, sets time points of a start and an end of the gear shifting based on the determined gear shifting progressing rate, and controls the gear shifting speed in the N-stage with reference to a gear shifting target speed and the transmission input speed in a section of the time points of the start and the end of the speed control.
